Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
Preferred embodiment one：
This preferred embodiment provides a kind of hot tank zero-pressure formula Drinking fountain.As shown in figure 3, the hot tank zero-pressure formula Drinking fountain includes
Outlet pipe 1, hot tank 2 and waste pipe 3, outlet pipe 1 is connected to the water side of hot tank 2, and waste pipe 3 is connected to the import of outlet pipe 1
And outlet between, waste water electromagnetic valve 31 is provided with waste pipe 3；When the outlet that hot tank 2 is in heated condition and outlet pipe 1 is closed
When closing, in hot tank 2 plus thermal expansion water via discharging via waste pipe 3 again after the part pipeline of outlet pipe 1.
The hot tank 2 of the Drinking fountain is connected to waste pipe 3 and in hot tank 2 in heated condition but outlet pipe 1 by pipeline
During port closing, plus the water of thermal expansion is discharged via waste pipe 3, timely pressure release, it is ensured that pressure remains zero in hot tank 2,
Prevent to cause the cyclic fatigue stress of the tank body of hot tank 2 because of boosting, blood pressure lowering, cause the tank body of hot tank 2 to crack.In waste pipe 3
On be provided with waste water electromagnetic valve 31, solve existing apparatus causes heat because capillary tube or pressure release valve module there are threshold value in itself
The problem of zero pressure cannot be realized in tank 2.
Pressure-detecting device is provided with hot tank 2, respectively signal is connected to control for waste water electromagnetic valve 31 and pressure-detecting device
Device processed.The mode by relief valve pressure release in existing apparatus is changed to switch pressure release by solenoid valve control in the present embodiment
Mode, pressure release is more thorough, is not affected by running water pressure, the volume of hot tank 2, heating-up temperature and valve threshold value, is truly realized
Zero-pressure is designed and the moment keeps zero-pressure.
It is provided with waste water electromagnetic valve 31 and pressure-detecting device and waste water electromagnetic valve 31 and pressure-detecting device difference signal
After being connected to control device, except because heating causes pressure in hot tank 2 to be more than zero when plus thermal expansion water energy via the row of waste pipe 3
Beyond going out, in hot tank 2 because any reason (such as ambient temperature rises sharply, tank in be mixed into expansive gas or liquid etc.) causes tank
Interior pressure may be by the pressure release of waste pipe 3 when being more than zero, better ensure that hot tank 2 is in all the time zero-pressure state.
In order to further improve control accuracy, water solenoid valve 11, water solenoid valve 11 are provided with outlet pipe 1
Between the junction 5 of water tap 4 and waste pipe 3 and outlet pipe 1.Minimum leaving water temperature can be set in this structure,
When water temperature is less than the numerical value in hot tank 2, water solenoid valve 11 is closed, even if open water tap 4 also will not go out
Water, it is to avoid the too low water of user's mispick water temperature.
On the basis of said structure, hot tank zero-pressure formula Drinking fountain also includes heat exchanger 7, the water inlet in heat exchanger 7
Heat exchange is carried out between pipe 8 and outlet pipe 1.Almost 100 DEG C of the water flowed out from hot tank 2 in heat exchanger 7 with water inlet
Tap water in pipe 8 carries out heat exchange, improves the temperature intake in water inlet pipe 8, reduces the energy consumption of the heating of hot tank 2；Water outlet
Coolant-temperature gage in pipe 1 after heat exchange slightly lower, and closer to consumption temperature, user can be avoided surprisingly to be scalded.
The concrete structure of heat exchanger 7 is not limited, and can realize that the water in outlet pipe 1 and water inlet pipe 8 carries out heat exchange.It is excellent
Choosing, outlet pipe 1 is located in the middle part of water inlet pipe 8 in heat exchanger 7, and water outlet and the heat exchange area intake are bigger, and heat is handed over
Change in hgher efficiency.
In order to further improve the heat exchange amount between water outlet and water inlet, the outlet pipe 1 in heat exchanger 7 can be designed
In broken line, curve or helical form, water inlet pipe 8 is wrapped in the outside of outlet pipe 1.By extending the contact with water inlet pipe 8 of outlet pipe 1
Length improves heat exchanger effectiveness increasing heat exchange area.
The control method of the hot tank zero-pressure formula Drinking fountain is when pressure value is more than the outlet pass of zero and outlet pipe 1 in hot tank 2
When closing, hot tank 2 is communicated to air via the part pipeline and waste pipe 3 of outlet pipe 1.
Specifically, when hot tank 2 is being heated and water tap 4 is closed, entering water electromagnetic valve 81 is closed, waste water electromagnetic valve
31 open, hot tank 2 and atmosphere, plus the water Jing waste pipes 3 of thermal expansion flow out, not pressure-bearing in hot tank 2.
When hot tank 2 is being heated and water tap 4 is opened, entering water electromagnetic valve 81 is opened, and water solenoid valve 11 is opened,
Waste water electromagnetic valve 31 is closed, and boiled water flows out from water tap 4, and pressure is zero in this intermittent fever tank 2.
When the heating of hot tank 2 is finished in keeping warm mode and water tap 4 is closed, entering water electromagnetic valve 81 is closed, water outlet
Electromagnetic valve 11 is closed, and waste water electromagnetic valve 31 is closed.In view of hot tank 2 remains that pressure is zero (heat in heating process previously
Tank 2 is communicated always with air), the pressure inside the tank in keeping warm mode after heating is finished of hot tank 2 will not increase, so now can keep
In zero-pressure state；The purpose for closing waste water electromagnetic valve 31 is to prevent the antibacterial in waste pipe 3 from entering in pipeline.
When the heating of hot tank 2 is finished in keeping warm mode and water tap 4 is opened, entering water electromagnetic valve 81 is opened, water outlet
Electromagnetic valve 11 is opened, and waste water electromagnetic valve 31 is closed, and boiled water flows out from water tap 4, and pressure is zero in this intermittent fever tank 2.
Preferred embodiment two：
This preferred embodiment provides a kind of hot tank zero-pressure formula Drinking fountain, and its structure is essentially identical with preferred embodiment one.No
It is with part：As shown in figure 4, being provided with three-way valve 6 in the junction 5 of waste pipe 3 and outlet pipe 1.In unmanned water intaking three
Port valve 6 automatically connects the leading portion of outlet pipe 1 with waste pipe 3, it is ensured that can be the pressure release of hot tank 2 by waste pipe 3, it is ensured that hot tank 2
All the time it is in zero-pressure state；When someone fetches water, three-way valve 6 automatically connects the leading portion of outlet pipe 1 with back segment, opens faucet
Switch 4 just can now still ensure that hot tank 2 is in zero-pressure state with water receiving.
On the basis of said structure, can non-return valve 32 be set on waste pipe 3, for preventing return of waste water.
